Marked LED filament lamps can be dimmed - not all dimmers can dim LED lamps. Flickering of LED lamps is often noticeable when the load falls below the specified minimum. We cannot guarantee the functioning of these lamps.
The color temperature (light color) of the illuminant has a great influence on the atmosphere in a room. Each light source is composed of spectral colors. The sum of these colors results in a (different) white, which is perceived as "warm", "neutral" or "cool". The unit of measurement for color temperature in Kelvin (K).
Color temperatureWe offer bulbs from 1800 Kelvin (very warm) to 3000 Kelvin (neutral). Illuminants with 2200 Kelvin come closest to the original tungsten illuminants in color appearance.
Color rendering CRI
A traditional light bulb impresses with a color rendering value of 100; the highest possible value - the perfect color rendering analogous to sunlight. Many LED bulbs have a CRI of 80 or below and do not come close to the premium models in terms of color rendering, but are cheaper to buy. The majority of our Led Filament bulbs achieve an excellent color rendering index (CRI) of over 90 or even 95 and thus a very high quality of light. You can find the color rendering index (CRI) of each bulb in our online store in the product description. It is also noted on the product packaging.
